The molar mass of a substance/chemical is the mass of the sample substance divided by the amount of substance in that sample.

Explanation:

In order to calculate the atomic mass of a substance we first obtain the atomic weight of the substance from the periodic table.
Then we count the number of atoms of the substance and multiply it with the individual atomic mass.

Molar mass of Citric Acid ( H3C6H5O7) is 192.1235 g/mol

It is calculated as :

Molar mass of C₆H₈O₇ = 6(atomic mass of C) + 8(atomic mass of H) + 7(atomic mass of O) = 6(12.0 g/mol) + 8(1.0 g/mol) + 7(16.0 g/mol) = 192.0 g/mol.

Molar mass of baking soda (NaHCO₃) is 84.0 g/mol

Molar mass of NaHCO₃ = (atomic mass of Na) + (atomic mass of H) + (atomic mass of C) + 3(atomic mass of O) = (23.0 g/mol) + (1.0 g/mol) + (12.0 g/mol) + 3(16.0 g/mol) = 84.0 g/mol.

True or False:

lesya [120]

Answer:

False

Explanation:

Mendeleev was the first scientist to arrange the element in such a periodic order but there was a mistake that he arranged in increasing order of mass.
Today we use the periodic table given by Henry Mosley where atomic no is first priority

According to the vsepr model the arrangement of electron pairs around nh3 and ch4 is

bazaltina [42]

The arrangement of electron pairs around CH4 and NH3, According to the VSEPR model is the same, because in each case there are the same number of electron pairs around the central atom. So the NH3 and CH4 arrangement of electron pairs is the same because in each case there are the same number of electron pairs around the central atom.

Describe the theory of plate tectonics

miskamm [114]

Answer:

The theory of plate tectonics states that the Earth's solid outer crust, the lithosphere, is separated into plates that move over the asthenosphere, the molten upper portion of the mantle. Oceanic and continental plates come together, spread apart, and interact at boundaries all over the planet.
